Define the concentration units mass percent and molarity.

Problem 15Q

Define the concentration units mass percent and molarity.

Solution 15Q: Here, we are going to discuss about the mass percent and molarity.

Step1: The molarity of a solution is defined as the amount of solute divided by the volume of solution in litres. It is simply defined as the moles of the solute per litre of solution. It is denoted by ‘M’.

Molarity (M) =amount solute (in mol)/ volume solution (in L)

The unit of molarity(M) is mol/L
